I will agree with the other posts here. I owned an evo 200.2 running on Maggies and it performed very well. Very clean, balanced and detailed. There were times when I thought the amplifier almost too clean and/or neutral but, isn't this what the amp is suppose to do?
On electrostatic speakers I was less enamoured in that the evo sounded very lean and brittle, though still squeaky clean and absolutely no grit. Just a lack of fullness to the sound. But this was not a problem on my Maggies.
As you are aware, the evo2 is suppose to be a improvement on the evo 200.2.
My advice, go for it. And, think about the BC preamp that goes with it (pre-1 or whatever the model is).
